Saxenda vs Wegovy: what is the difference?

Saxenda is the brand name for liraglutide 3 mg, a GLP-1 receptor agonist taken once daily. Wegovy is the brand name for semaglutide 2.4 mg, taken once weekly. Both are FDA-approved for chronic weight management, but they differ in effectiveness, dosing, and convenience.

Wegovy has largely replaced Saxenda as the preferred injectable weight-loss medication because it produces more weight loss with weekly dosing. However, Saxenda still has a role for some patients.

How do Saxenda and Wegovy work?

Both medications are GLP-1 receptor agonists. They reduce appetite, slow stomach emptying, and improve blood sugar control. The key difference is the molecule:

Liraglutide (Saxenda): Shorter-acting, requires a daily injection.
Semaglutide (Wegovy): Longer-acting, requires a weekly injection, and produces stronger average weight loss.

Clinical results: Saxenda vs Wegovy weight loss

Clinical trials show a clear difference between the two medications:

Saxenda produced about 8% average weight loss at 56 weeks
Wegovy produced about 14.9% average weight loss at 68 weeks

In other words, Wegovy produces nearly twice as much average weight loss as Saxenda. This is why most providers and patients prefer semaglutide when available.

Dosing schedules

Saxenda is injected once daily, usually in the abdomen, thigh, or upper arm. The dose starts at 0.6 mg and increases weekly to 1.2 mg, 1.8 mg, 2.4 mg, and finally 3 mg.

Wegovy is injected once weekly. The dose starts at 0.25 mg and increases every 4 weeks to 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg.

Many patients strongly prefer weekly injections because they are easier to remember and less disruptive to daily life.

Side effects

Both Saxenda and Wegovy cause similar gastrointestinal side effects:

Nausea
Diarrhea
Vomiting
Constipation
Decreased appetite

Daily injections with Saxenda may cause more injection site reactions. Wegovy's longer half-life may cause side effects to last slightly longer but often improves tolerability overall.

Cost without insurance

Without insurance, Saxenda and Wegovy both retail for approximately $1,300 to $1,400 per month. Insurance coverage varies widely, and weight-loss medications are often not covered.

For people paying cash, compounded semaglutide through telehealth programs is much cheaper than brand-name Wegovy or Saxenda, typically $150 to $350 per month.

Can you switch from Saxenda to Wegovy?

Yes, many patients switch from Saxenda to Wegovy under medical supervision. Common reasons include better weight loss on semaglutide, fewer injections, or side effect concerns. A clinician will usually restart titration at a low Wegovy dose.
